3.3.3. Accuracy
Accuracy of the proposed HPLC determination was evaluated
from the assay results of the components. Accuracy was done by
performing the assay of samples and calculated the peak area
responses of different samples by recovery method.
Appropriate portions of stock solution were spiked into blank
placebo matrix to produce concentration of 80.0 to 120.0% of
target level. Mean recovery of spiked samples was 99.30% for
sodium hyaluronate shown in Table 1
